“…Lineus viridis (Müller, 1774) is among the most common species of the Northern Hemisphere (Gibson 1995). In the past, L. viridis was routinely confused with its sibling species, Lineus ruber (Müller, 1774), and it was not until fairly recently that they have been recognized as two, separate species (Gontcharoff 1951;Rogers et al 1993Rogers et al , 1995see Friedrich (1979) and Gibson (1995) for an evaluation of older accounts).…”

“…Nemerteans (ribbon worms) are top predators feeding on various prey organisms (crustaceans, annelids and mollusks) (Thiel and Kruse 2001 and references therein) and are common in marine habitats (Gibson 1972(Gibson , 1995. While the role of nemertean worms as a predators and prey organisms has been studied in a moderate number of species (Nordhausen 1988;Thiel and Reise 1993;Thiel et al 1995Thiel 1998;McDermott 2001;Thiel and Kruse 2001;Caplins and Turbeville 2010), studies of the life cycle of this taxon, comprising some 1275 species (Kajihara et al 2008), have been done on a broader scale for only a handful of species (for reference Thiel and Junoy 2006).…”

Lineus viridis is a common nemertean species of North-Atlantic intertidal sand flats. Its mating behaviour is peculiar insofar as this species is reported to be polyandric. However, detailed information on this topic is lacking. In order to get more data on the reproduction, oogenesis and life history of this species, a population in the Wadden Sea on the Isle of Sylt (North Sea) was studied between 2005 and 2011. We conducted regular surveys, during which we sampled, measured and recorded the sex status of 25-100 individuals at each sampling event; at least three individuals were fixed for histological studies at each sampling date. In addition, animals were kept in the laboratory for 3 years to complement field data on sexual identity. Lineus viridis was found to reproduce annually in several successive year; the females are significantly larger than the males. Oogenesis starts in spring, shortly after the preceding reproductive period, and continues until the end of December. Spermiogenesis starts in late autumn and also ends late in December. During mating, several males are generally found crawling on a single female, which forms a cocoon that encloses both the female and the associated males. Fertilization is internal. While females discharge all of their eggs during a single mating event and lose more than 40% of their wet weight, males only empty a few of their gonads, and are thus able to fertilize more than one female. Our study clearly shows that Lineus viridis is a perennial, iteroparous species with a pronounced sexual size dimorphism. During this long-term study, no evidence for sequential hermaphroditism has been found. The observed polyandric mating system in this species raises further questions regarding mate and sperm competition that deserve additional research.

“…Sundberg et al 2009;Taboada et al 2013), the latter traditionally considered as the diagnostic characters to differentiate among taxa (Sundberg et al 2016a). However, most of the described nemertean species are known to have inadequate taxonomic descriptions, either lacking or having inadequately documented histological characters and/or lacking proper descriptions of their external features that are commonly lost as a preservation artefact (Gibson 1995). To solve this taxonomical conundrum, a group of nemertean taxonomic experts have recently proposed that traditional histological techniques to describe internal characters are not essential for identification and description purposes (Sundberg et al 2016a).…”
